What is a hazard tree?

A hazard tree is defined as one that poses a significant risk of causing injury, damage, or disruption due to its condition or placement. This designation is typically based on factors such as the tree's structural integrity, disease status, or proximity to people and infrastructure. When evaluating trees for hazards, professionals consider characteristics that could lead to parts of the tree failing or the tree itself toppling over, especially in adverse weather conditions or if the tree is located in a high-traffic area.

The other options outlined refer to trees in different contexts. A healthy tree that does not pose any threat is simply a safe, stable plant and does not pertain to the concept of hazard trees. A recently planted tree is in an establishment phase and, while it may require care, poses different considerations. Lastly, a tree producing flowers or fruit indicates its reproductive health and growth patterns, which are unrelated to the risk it may present to its surroundings. Thus, only the first option aptly captures the essence of what constitutes a hazard tree.
